IMPRUVEMENTINTREATING TARHED ROPE, CORDAGE, AND THE LIKE, FOR THEMANUFACTURE OF PAPER STUCK, 80c.

Specification forming part of Letters Patent No. 119,186, datedSeptember 19, 181

To all whom it may concern:

. ing is a specification:

My invention consists in subjecting to the vapors of hydrocarbon tarredropes, cordage, &c., with the view of rendering it available as paperstock.

In applying old tarred ropes, cordage, &c., generally termed junk, tothe manufacture of paper much difficulty is experienced in depriving thematerials of the tar, pitch, and other foreign matter with which thefibrous strands are impregnated. I have found that the best means ofeffecting this is to subject the ropes, &c., to the action ofhydrocarbon vapors, and especially to these vapors under heat andpressure. Although many different appliances may be adopted in carryingout my invention, I prefer to use a closed vessel capable ofwithstanding apressure of from ten to thirty pounds per square inch, andon a perforated plate in this vessel to place the rope,

. cordage, spun yarn, or old sails.

The vapors of hydrocarbon-by preference, gas

' oline, benzine, benzole, or naphtha-may be in- V troduced into thisvessel below the perforated plate, or the vapors may be generated in thebottom of the vessel itself. These vapors permeate the material and soondissolve the tar and pitch, as well as the grease with which the strandsare impregnated, and the fibers, after washing them, are available forp( per stock, and in many cases, where the fibers are not rotten, theymay be reconverted into ropes, cord-age, &c. The vapors maybe carriedoff through a pipe to a condenser and returned to the still in the formof liquid hydrocarbons, which may be again vaporized and used as before.A loaded valve in the vapor-pipe Will serve to maintain any desiredpressure in the vessel. WVithout confining myself to any specificapparatus for practising my invention,

I claim 4 subjecting tarred rope, cordage, &c., to the action ofhydrocarbon vapors, substantially as and for the purpose set forth.

In testimonywhereof I have signed my name to this specification in thepresence of two subscribing witnesses.
